Accelerated healing factor: Lex' accelerated healing exceeds those of most speedsters, due to his very potent connection to the Speed Force. Being from the future and still youthful, means he is also extremely long lived due to his accelerated healing.

Electrokinesis: When moving at superhuman speeds, Lex generates white lightning. He is also capable of projecting electrical arcs, although it is unknown if he must absorb a sufficient amount of energy to do this, to which he uniquely is able to absorb any electricity launched at him and can then redirect it.

Superhuman perception: Lex is easily capable of keeping up with and perceiving the movements and actions of speedsters.

Superhuman strength: Lex possesses a level of increased strength, able to lift and drag a fully-grown man off the ground by their throat, all with a single hand.

Speed Force sense: Lex can sense the speed force in another speedster's system to locate them at any place or time.

Superhuman agility: Lex possesses superhuman bodily coordination, balance, equilibrium, and dexterity. He is able to change direction immediately, thus allowing him to make sharp turns and easily maneuver while moving at immense speed.

Superhuman durability: Lex possesses inhuman resilience to injury, taking attacks and exertion much easier than normal humans and surviving impacts that would easily harm or kill a normal person.

Bodily vibration: Lex can vibrate different body parts for various effects. Vibrating his entire body can mask his form from being clearly perceived or distort his vocal cords to disguise his voice.

Geokinesis: Lex is somehow capable of generating earthquakes with his speed. His ability to create earthquakes is likely due to the absurd amount of kinetic energy he transfers into the ground with every step he takes.

Superhuman momentum: Lex can generate great amounts of physical force through the kinetic energy his immense speed generates. This allowed him to knock several cops into the air when running past and killing them when he first encountered the younger Lex.

Superhuman reflexes: Lex' reflexes are enhanced to superhuman levels, allowing him to easily react to danger and events.

Shock waves: Lex possess the ability to create very powerful sonic booms and shock waves with just the clap of his hands.

Energy construct creation: Lex can focus his Speed Force energy to create constructs, such as suits made of pure Speed Force energy. He created his White Flash suit out of his Speed Force energy, which he can easily destroy/removes and recreate it.

Skilled hand-to-hand combatant: Lex is a capable fighter as evidenced by his rapid victory over other speedsters like the younger Lex. He uses his extraordinary speed to land powerful blows and throw his opponents around with lots of momentum.

Cold temperatures: Because speed is produced by a build-up of heat in the target's atoms, Lex is vulnerable to extreme cold temperatures. Under these conditions, Lex' speed will be greatly reduced. Also, direct exposure to such cold will temporarily stunt his healing capacities.
